This was an interesting thread. I was a bit puzzled by some bits, but only based on my two experiences of taking a Filipina out of the country.
Sept 2012: I took a Filipina out of the country for 3 months, after only having met her 2 weeks earlier, but had known her on the internet for 2 months.
Nov 2014: I took another Filipina out of the country for 3 months, but I had met her 6 months before.
Neither time was a problem, but both times just a few quick questions to her from an Immigration person at the airport. No proof of anything was asked for.
No hotel reservations needed, but return tickets were in our possession. Of course I was actually with her, so this is different than for some cases mentioned in the thread.
